CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of Korean Patent Application Nos. 10-2020-0139210 filed on Oct. 26, 2020 and 10-2021-0044808 filed on Apr. 6, 2021, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION Field of the Invention

The present disclosure relates to a cosmetic brush and more particularly, to a cosmetic brush capable of assembling a complete product without using an adhesive in a process of manufacturing a brush.

Description of the Related Art

In general, cosmetics used for make-up are formed in a liquid, a solid, and a mixed state of the liquid and the solid. Among them, in order to apply the solid cosmetics on the face, brushes having various shapes and sizes have been developed and used.

That is, the above-described brushes are provided so that the cosmetics made of solid powder may be coated on bristles of the brush to be properly applied on the face and the like. The brush consists of a handle capable of being griped by a user and a brush provided at a front end of the handle and consisting of a plurality of bristles.

In the related art, the brush is coupled to the handle by using chemical materials such as an adhesive. In this case, the adhesive may be formed of a chemical material, which may have a harmful effect on the human body, and considering this, in the case of using an adhesive harmless to the human body, there is a problem that the manufacturing cost increases.

In addition, since the adhesive is a material that is vulnerable to heat, there is a problem that when the adhesive is exposed to heat, an adhesive portion is detached so that the durability deteriorates.

The above-described technical configuration is the background art for helping in the understanding of the present disclosure, and does not mean a conventional technology widely known in the art to which the present disclosure pertains.
